WebAs is characteristic to members of the L4 microkernel family, seL4 uses ‘‘synchronous IPC’’. This means a rendez-vous communication model, where the message is exchanged when both sender and receiver are ready. If both are running on the same core, this means that one partner will block until the other invokes the IPC operation. Web14 jan. 2024 · The microkernel differs from an executive in how the IPC services are used to extend the functionality of the kernel with additional, service-providing processes. Since the OS is implemented as a team of cooperating processes managed by the microkernel, user-written processes can serve both as applications and as processes that extend the …

Web14 jan. 2024 · Interprocess Communication plays a fundamental role in the transformation of the microkernel from an embedded realtime kernel into a full-scale POSIX operating system. As various service-providing processes are added to the microkernel, IPC is the “glue” that connects those components into a cohesive whole. WebStarting from the IPC implementation in L4/Alpha, we also implemented a lower-level communication prim-itive, similar to Exokernel’s protected control trans-fer [12], to find out whether and to what extent the L4 IPC abstraction can be outperformed by a lower-level primitive.
